Hi, @TerrenceRao, thank you for reaching out to Atlassian Community. 

As we will need to know the public ssh key to further investigate this case, I have created an internal ticket for you using the email of your community account, so you don't have to share this information here. 

You should have received an email with a link to the support ticket. Just in case you haven't received it, please feel free to let me know and I can post the ticket URL here. The ticket will be visible only to you and Atlassian staff, no one else can view its contents even if they have the URL.

Please feel free to let me know if you have any questions.

Kind regards,
Caroline

Bitbucket only allows for the SSH pub keys to occur once. They have to be unique. This means that it is highly likely that this key has been added to another account. 

Most people run into this when trying to add their work/personal/deploy key to the opposite or multiple accounts. It is best practice to create seperate keys for those accounts.

However, there is not enough information in your post to help you further. The problem you describe has been posted before though. A quick search through the forums gave me some of the following results:

I hope these will help you solve your problem.
